F-DGS’s DEIMOS CO2.FREE Air Gas generators is specifically designed for use with FT-IR spectrometers to provide a purified purge and air bearing gas supply from compressed air.

The unit provides instruments with CO2 free compressed air at less than -70°C (-94°F) dewpoint with no suspended impurities larger than 0.01 micron 24 hours/day, 7days/week.

The DEIMOS CO2.FREE is available with integrated oil free air compressor using the Energy Saving Technology mode (EST). It is extremely compact and quiet in operation.

The generator is controlled using the latest color touch screen technology to display the process in real time, inlet / outlet pressure, Air Flow and status of the system with remote access for diagnostic control.

A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.

The CO2 FREE Air gas generator generates cleaner background spectra in a shorter period of time and more accurate analysis by improving the signal-to-noise ratio.
The investment can be paid back in less than one year.

CO2 FREE Air gas produced at low pressure and ambient temperature removes the need for high pressure cylinders.

Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere.
